Unformatted text preview: Refrigerators and Ozone Depletion Structure of the Atmosphere Ozone in the Troposphere and Stratosphere Ozone Depletion Health/Environmental Effects Summary and Conclusions Sunlight and the Electromagnetic Spectrum Shorter wavelengths contain more energy – UV. Ozone filters wavelengths below 290 nm. The Ozone Layer Absorbs Harmful UV Rays Filtering is protective for all life forms. Ozone in the Troposphere – Undesirable Produced by electric motors and reactions between NOx and volatile organic chemicals. Sources of NOx include engines and other combustion. Sources of VOCs include engine exhaust and green plants. Ozone in the Stratosphere – Desirable Ozone filters UV, converting it to less dangerous IR. Ozone Layer and the Atmosphere Normally temperature and pressure are directly related. Altitude is usually accompanied by a drop in pressure....
